In the circuit shown, calculate the current I3 . Give value in the directions shown (e.g. if the actual direction of current is opposite to one of these, write it as a negative value). Write answer in milli-amperes.
R1 = 0.6 kilo-ohm, R2 = 0.8 kilo-ohm, R3 = 1.1 kilo-ohm, R4 = 0.6 kilo-ohm
R5 = 0.4 kilo-ohm, V1 = 3 volts, V2 = 1 volts
